To set the digital display and synchronize the display with the time type wheels, do the following: 1. Connect the power source. 2.
8 - LT Series Operations Manual ADJUSTING PRINT IMPACT Print impact may be set to any desired level, from very hard to very light. The impact adjuster is located on the bottom of the unit. Using a small flat head screwdriver, turn the adjuster to the right to increase or left to decrease the impact.

The trigger assembly tells the unit how far the document must be inserted before activating the stamp.
11 - LT Series Operations Manual CHANGING THE RIBBON LT Series time stamps use a silk ribbon for long-lasting, high-quality imprints. To avoid damaging the unit, use only a #20-S ribbon. To change the ribbon: 1. Disconnect the power source. 2. Remove the top cover. Remove the frame locking pin and lift the top frame (as described on Page 6, Figure 2). 3. Pull the front spool plunger knob (Figure 8, Number 1) away from unit. While holding the knob, slide the ribbon to the left and out. 4.

Remove top cover and frame locking pin as described on Page 6. Lift top frame. 3. Locate the Fuse Holder Cap (Figure 9, Number 1).
